To all whom itmay concern:

Be it known that i, PHELoeANBu'ra D,

designed for use in connection with-a boiler for heating the water before it'enters the boiler.

Another object of the inventionis to provide a pre-heate'r so constructed that the exhaust from the engine may beutilized for heating said water before it enters I the boiler. W I

With the above'and other objects in view the invention has particular relation to cer: tain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure l is an end view of the pre-heater.

Figure 2 is a side view. D

Figure 3 is a vertical sectional View taken on the line 3-3 of Figure 2, and

Figure a is a vertical sectional view taken I on the line H of Figure 1.

Referring now more particularly to the drawings, the numeral 1 designates the outer shell, or casing which may be of any desired contour and which is preferably constructed of sheet metal. 'To one side of this casing there is secured a vertical float chamber 2. The numeral 3 designates an inlet water pipe through which water is admitted, and this pipe separates into the branch pipe t, 4;, which enters through the top of the casing. Underneath the discharge ends of these branch pipes there is located a series of pans 5, 5, 6, 6, 7, These pans are supported on suitable cross rods 8, whose ends are supported on the cleatsr9,

which are fastened on the inside of the side walls of the casing. The'pans of each series are enlarged downwardly, that is each pan is somewhat larger than the one immediately above it, so that the overflow of water from any pan will be caught by the one beneath it. These pans stand full of water and the overflow from them keep the casing filledwv'ith water up to level of the overflow pipe 10.

At one end of the casing there is an enclosed steam chamber 11 into which the exhaust gases or steam enters through the pipe 12. At the oppositeend of the casing" there is a"transverse partition plate 13 ex from side to side of the casing and tendin extending from the bottom thereof up slight ly above the overflow pipe 10, thus forming a chamber 14 which is 'open'at the top and from the bottom of. which there leads a drain pipe 15 through which condensed I water may be drained from said last mentioned chamber. The chambers 11 and 14 are connected by tubes' 16, The steam orexhaust gases entering. the chamber 11 pass through said tubes into the chamber 14 and pass thence up around the pans and out through the discharge pipe 17. It is to be, noted that the tubes 16 are submerged in water and heat the same, and the pans 5, 6, and 7 are also filled with water, which is heated by the hot steam, or hot gases, by

vwhich they are enveloped. A glass gage 18' is connected into the casing above and below the tubes 16. This is provided for the purpose of ascertaining the amount of water in the casing. Leading from the bottomof.

the casing there is an outlet line 19 which leads to the pump by which the heated saidchamber it will lift the float and close' said valve to shut off the inflow of water and as the water falls in saidr chamber the 7 means for controlling the inflow of water,

a pan in the upper part of the casing aligned underneath the discharge end of said water pipe, an outlet pipe leading from said casing, chambers on opposite sides of the casing, one of. which is open on one ide,

"an inletentering the other chamber, av conduit connecting said? 7 chambers providing; for; the passage of a heating medium therethrough.
